| class | pucch_resource_manager |
| Class that manages the cell allocation of PUCCH resources across UEs. The correct functioning of pucch_resource_manager is based on the following assumptions: (i) Each UE has max 8 PUCCH F1 and max 8 PUCCH F2 dedicated to HARQ-ACK reporting. (ii) Each UE has max 1 SR-dedicated PUCCH F1 resource and max 1 CSI-dedicated PUCCH F2 resource. (iii) The cell PUCCH resource list can have max 128 PUCCH resource, including all formats; at cell level, there is no constraint on how many resource must be F1, F2, or for SR or for CSI. (vi) UEs can have different PUCCH resource lists; however the PUCCH resource ID is unique with the cell. This implies that if two UEs have the same PUCCH resource within their lists, their PUCCH resource ID must be the same. (v) Indexing of the PUCCH F1 and PUCCH F2 resources for HARQ-ACK reporting must be contiguous within the F1 group and with F2 group. However, the last PUCCH F1 group resource's and the first PUCCH F2 group resource's indices need not be contiguous. E.g., PUCCH F1 indices (for HARQ-ACK reporting) = {0, ..., 7}, and PUCCH F2 indices (for HARQ-ACK reporting) = {10, ..., 17}. More... | |

| Divides a bitset of size "S" into "M" smaller bitsets, where each bitset has length "L=S/M". A bitwise-or operation is performed across bitsets. At the end, a slice with an offset "O" and length "K" is taken from the bitset of length "L" that resulted from the bitwise-or operation. This operation is equivalent to reshaping an array of bits of size "S" into a matrix of dimensions "(M, L)" and applying an "or" operation across all bits of each column. The resulting array of "L" bits, is then sliced with an offset "O" and length "K". The operation asserts if "S % L != 0". E.g. Consider the bitset 1000 0100 0000 1001 (S=16), L=4, O=1, K=2.

Detailed Description
This header is currently used only by the MAC to compute extra SSB parameters (needed for scheduling) from those provided by DU.
This factory header file depends on the GTP-U tunnel interfaces (see above include list). It is kept separate as clients of the GTP-U tunnel interfaces do not need to call factory methods.
This factory header file depends on the PDCP entity interfaces (see above include list). It is kept separate as clients of the PDCP entity interfaces dont need to call factory methods.
This factory header file depends on the SDAP interfaces (see above include list). It is kept separate as clients of the SDAP interfaces dont need to call factory methods.

Direct Current (DC) offset, in number of subcarriers. See "txDirectCurrentLocation" in TS 38.331.
The numerology of the active UL/DL BWP is used as a reference to determine the number of subcarriers of the DC offset. The DC offset value 0 corresponds to the center of the SCS-Carrier for the numerology of the active UL/DL BWP. The relation with the TS 38.331 "txDirectCurrentLocation" parameter is, therefore, given by: dc_offset = txDirectCurrentLocation - 12 * N_RB / 2, where "N_RB" is the number of RBs of the SCS-Carrier. In case the DC offset falls within the SCS-Carrier boundaries, its value should range between {0,...,12 * N_RB - 1}.

- Parameters
-
[in] expire_timeout_slots Number of slots after which resource grids are expired. [in] async_executor Asynchronous task executor for setting the grid to zero. [in] grids Resource grids, ownerships are transferred to the pool.
- Returns
- An asynchronous resource grid pool.

◆ create_radio_factory()
| std::unique_ptr< radio_factory > srsran::create_radio_factory | ( | std::string | driver_name | ) |
Creates a radio factory by selecting an existent factory or loading the appropriate dynamic library.
By default, this function creates a radio factory from the statically linked ones (i.e., uhd).
If the driver_name does not match with one of the statically linked factories, this function dynamically loads a shared library corresponding to the specified driver name and retrieves the factory creation function from it.
The naming convention for the shared library is as follows: if the driver name is custom, the library name is expected to be libsrsran_radio_custom.so. The factory creation function within the dynamic library is expected to implement the function prototype create_dynamic_radio_factory.
Ensure that the LD_LIBRARY_PATH environment variable includes the path where the dynamic libraries are located.
- Parameters
-
[in] driver_name Selects the type of radio factory for example uhd or zmq.
- Returns
- A valid radio factory if the factory is successfully created, otherwise
nullptr.

78 // Convert driver name to lower case.

Helper function to generate DMRS sequences.
This function generates DMRS sequences based on a pseudo-random sequence generation. It generates nof_dmrs_per_rb for every active resource block given in rb_mask and skips the nof_dmrs_per_rb for every inactive resource block.
- Parameters
-
[out] sequence Provides the destination storage for the generated sequence. [in,out] prg Provides the pseudo-random generator to use. [in] amplitude Provides the sequence amplitude. [in] reference_point_k_rb Indicates the RB index for reference. [in] nof_dmrs_per_rb Indicates the number of DMRS to generate per active RB. [in] rb_mask Indicates the active resource blocks.
- Note
- It assumes that the pseudo-random generator is initialized.
- The sequence size must be consistent with the number of active RBs and the number of DMRS per RB.

◆ fold_and_accumulate() [2/2]
template<size_t N2, size_t N, bool LowestInfoBitIsMSB>
|
inlinenoexcept |
Divides a bitset of size "S" into "M" smaller bitsets, where each bitset has length "L=S/M". A bitwise-or operation is performed across bitsets. At the end, a slice with an offset "O" and length "K" is taken from the bitset of length "L" that resulted from the bitwise-or operation. This operation is equivalent to reshaping an array of bits of size "S" into a matrix of dimensions "(M, L)" and applying an "or" operation across all bits of each column. The resulting array of "L" bits, is then sliced with an offset "O" and length "K". The operation asserts if "S % L != 0". E.g. Consider the bitset 1000 0100 0000 1001 (S=16), L=4, O=1, K=2. This function performs the following steps:
- Break the bitset into M=S/L=4 parts: {1000, 0100, 0000, 1001}.
- Bitwise-or all the M parts: 1101.
- Slice the bitset obtained in 2. with offset O=1 and slice length K=2: 10.
- Template Parameters
-
N2 maximum bitset size for returned bitset.
- Parameters
-
[in] other original bitset of length "S". [in] fold_length length of each folded bitset "L". [in] slice_offset offset from where to slice each fold "O". [in] slice_length length of the slice taken from each fold "K".

◆ get_allocator_ring_size_gt_min()
Retrieves the resource grid allocator ring size greater than given minimum value.
- Remarks
- 1. The implementation of circular ring based resource allocator only works correctly if we set a ring size which satisfies the condition NOF_SLOTS_PER_SYSTEM_FRAME % RING_ALLOCATOR_SIZE = 0. The condition is placed to avoid misalignment between (last_slot_ind + slot_delay) slot point and slot point contained in ((last_slot_ind + slot_delay) % RING_ALLOCATOR_SIZE) slot, which occurs when slot point is close to NOF_SLOTS_PER_SYSTEM_FRAME value. Misalignment example: Assume NOF_SLOTS_PER_SYSTEM_FRAME = 10240 and RING_ALLOCATOR_SIZE = 37 At Slot point (10238) % 37 = Element at index 26 of slots array/vector is accessed, similarly Slot point (10239) % 37 = 27 Now, Slot point wraps around NOF_SLOTS_PER_SYSTEM_FRAME and is set to 0, this causes Slot point (0) % 37 = 0. Resulting in element at index 0 of slots array/vector being accessed rather than index 28.
- 2. The reason for choosing values 20, 40 and 80 for RING_ALLOCATOR_SIZE is because it holds the condition NOF_SLOTS_PER_SYSTEM_FRAME % RING_ALLOCATOR_SIZE = 0. for all numerologies.

Computes the required number of PRBs necessary to transmit a given payload size.
This function implements the inverse procedure of the TBS calculation procedure (as per TS38.214 Section 5.1.3.2) to derive the number of PRBs from a given payload in bytes.
- Parameters
-
[in] sch_config is a struct with the PDSCH configuration to compute the num. of PRBs. [in] max_nof_available_rbs is the maximum number or available of PRBs within the BWP. By default, this is set to the maximum number of RBs for FR1, as per Table 5.3.2-1, TS 38.104.
- Returns
- Returns a struct with the number of PRBs and the corresponding TBS. If the payload_size is greater than 478 bytes (3824 bits), it returns the number of PRBs and TBS corresponding to maximum allowed payload size of 478 bytes.

◆ ssb_get_k_first()

Calculates the position of the first SS/PBCH block subcarrier relative to Point A.
The result is expressed in units of subcarriers of SS/PBCH block SCS ssb_scs assuming that:
- the lowest subcarrier of the resource grid overlaps with Point A, and
- the resource grid SCS matches the SS/PBCH block SCS.
In other words, it is not possible to determine an SS/PBCH block position in the grid if the SS/PBCH block subcarrier offset does not match the position of the resource grid subcarriers. Because of this, the parameters must result in an integer subcarrier index of the SS/PBCH block SCS.
Assertions are triggered if:
- the provided SS/PBCH SCS and frequency range combination is invalid, or
- the result would point to a non-integer subcarrier index.
- Parameters
-
[in] fr Frequency range. [in] ssb_scs SS/PBCH block subcarrier spacing. [in] common_scs Higher layer parameter subCarrierSpacingCommon as per TS38.331 MIB. [in] offset_to_pointA Offset to Point A (see here for more information). [in] subcarrier_offset Subcarrier offset (see here for more information).
- Returns
- The index of the lowest subcarrier of the SS/PBCH block.

◆ to_span()
Provides a contiguous view of a byte_buffer. It is bound to the lifetime of the byte_buffer src and the temporary buffer tmp_mem, whichever is shorter. Important: tmp_mem must be at least as large as src.
The memory used for the result and the complexity depends on whether src is contiguous or not:
- Contiguous: Result is a view of the first and only segment of
src. - Non-Contiguous: Result is a view of
tmp_memin which all segments ofsrcare copied.
- Parameters
-
src Source byte_buffer. tmp_mem Temporary memory for a possible copy. Must be at least as large as src.
- Returns
- A contiguous view of the byte_buffer
